Please make sure you are on WiFi if possible and also use your desktop computer to download big files as it's more stable than downloading straight to your Android device.

Most bad downloads are caused by unstable internet connection. If you are using cellular 3G or 4G LTE to download, make sure you have good signal while downloading and try to not move your Android device during download.

All of our download servers are connected to Tier 1 100Mbps port so if you get bad downloads, your internet connection is probably unstable.
